Any other information on results incl. tables

The weight losses of the test substance at 110°C, 120°C, 130°C and 140°C were lower than the weight losses of hexachlorobenzene at the same temperatures. From this it was concluded that vapour pressure of the substance at 20°C (25°C) is lower than the vapour pressure of hexachlorobenzene at 20°C (25°C).

Applicant's summary and conclusion

Conclusions:
The vapour pressure of Broomdex at 25°C was determined to be <0.0069 Pa.
Executive summary:

The vapour pressure was determined using the isothermal thermogravimetric effusion method in a GLP study according to EC A.4, OECD 104 and OPPTS 830.7950. The vapour pressures of the substance at 20°C and 25°C were determined to be <0.0015 Pa and <0.0069 Pa, respectively.
